Which Hoverboard Racetrack did you prefer the best in Ratchet and Clank? Rilgar or Kalebo III?
It's quite difficult to pick which one is better because I thought they were both great racetracks overall. But, if I had to pick one, I would choose the one in Rilgar. It's not that visually appealing, but the layout design of the racetrack was really fun overall. I also liked the fact that you're racing a bunch of aliens that looks like Skidd McMarx (even if his name of species is unknown still), which is a supporting R&C character that I really like.
I would point out that Kalebo III had a more lively and beautiful design and you had so much space to ride your hoverboard with than in Rilgar, but there are certain segments of the track that would easily hit you right away such as explosive boxes, really tight ramp spaces and even poles too (if you're not on the upper level of the racetrack). Rilgar had stuff like that in its racetrack as well, but it was a bit easier to dodge those nuisances than the ones in Kalebo III.
